sounds like you have to go to a new store to get your shit mounted.
secondly i have never looked at a pair closely, but the best thing you can do is pull out a tape measure measure the enitre length of the ski, find exact center. From there then measure back to those lines on the ski.
See how far back they are from center.
Generally anything  0cm to 5cm back from center could be considered a "forward from traditional mounting point" and anything farther back then that is usually a traditional mounting point.
If you plan on using the skis in the park, mount on the line that is as close to center as marked.
If you don't really ski park that much, and this is your freeride, i ski forward 98% of the time mount on the line farther back.
And hopefully someone that actually owns a pair will tell you exactly wehat they did and how they like it.
